Patented Nov. 5, 1946 T um'reo. STATES PATENT- OFFICE MoNoLrrmc FLOORCONSTRUCTION Ignatz Adolf Kirchner, Vienna, Germany; vested in the AlienProperty Custodian Application November 3, 1933, Serial No. 238,682 InAustria November 4, 1937 simple and efie ctive suspension of suchcompression girder bodies on the ribs or girders by means of reinforcingirons which project out of said compression girder bodies. Thissuspension may be performed by various constructions and can be combinedwith additiona'fm'eans for 'suspending the compression girder bodies onthe ribs.

Other details of the invention shall be described with reference to theaccompanying drawing in which different forms ofconstructions= embodyingthe invention are illustrated. 1

Fig. 1 shows'in cross section a floor construction according to theinvention;

Fig. 2 shows a compression girder according to the invention inperspective view; and

Figs. 3 to 6 show modif cations of the mode of suspension'in afloor-construction according to Fig. l in cross section.

The embodiment according to Fig. 1 shows a rod 2 concreted into thecompression girder body I, said rod resting on the top of the girder 3and being embedded in the concrete poured between the girder topand thecompression girder body. As will be seen more clearly from theperspective view of Fig. 2, the compression girder bodies I may beprovided with recesses 4 in which engage the ends of the rods 2projecting beyond the top of the girder. In order that the compressiongirder bodies may all have a uniform shape, it is advisable for the rodsto be embedded in said bodies in a somewhat inclined position withrespect to the plane of symmetry thereof, so that the projectingportions of the rods cannot strike against one another when said bodiesare in position. At the places wher the rods 2 emerge from the girderbodies I, there may also be provided shoulders 5, as will be clearlyseen from Fig. 2. The rods 2 may be bent to hook shape at their freeends either before or after they have been placed in position, so thatthey engage over thetop of the girder 3 (see Fig. 3). The operation mayalso be carried out in such a manner that the compression girder bodiesare positioned on the.

4 Claims. (Cl. 72-68) 2 girders orribs with the rods'bent at one endonly, the other free end then being bent around the top of the othergirder.

Moreover, the rods 2 which ar bent over the top of the girders may begiven an additional upwardly bent portion 6 at their free ends, and saidupwardly bent portion 6 may serve for support-' ing the adjacentcompression girder body, as shown in Fig. 4, In this way, it is possibleto have a" double supportor mounting for the compression girderbodies;namely, firstly by means of the reinforcing iron proper on the top ofthe girder, and, secondly, with the bottom edge on "the bent or hookportion 6 of the reinforcing iron 2 of the opposite compre ss ion girderbody. In order to give good support, itis advisable in this case to makethe bent up portion of the free ends of the reinforcing irons only afterthe compression girder bodies have been placed in position.

" 'In addition to supporting the compression girders by means of theirreinforcing irons, it is also possible to employ supports provided onthe ribs or girders, thereby making-it possible to have a threefoldmounting for the compression girders.

Fig. 5 shows the combination of thesuspension 'by means of thereinforcingirons 2 with that obtained by usin gsupportin'g hooks lwhich; are positioned over the topsof the girders 3, As will be readilyunderstood, these supporting hooks may also be extended downwardly onone side of the girder and be used in known manner for suspending thplaster ceiling or the like. In this case, the hook I (Fig. 5) or a loop8 in the extended limb of the supporting hook is used for the ,mountingof the compression girder body. Also in the construction shown in Fig. 3an additional support for the compression girder body is indicatedconsisting of a bridge I!) which is arranged between the girders 3 andfastened on the top of the same by hooks I I.

In addition to the suspension by means of the reinforcing irons, themounting can also be effected on steps 9 of the girder 3, as will beseen from Fig. 6. l

The provision of several supporting elements for the compression girderbodies not only results in a better mounting, but also in a betterbinding action.

The construction according to the invention can also be executed in sucha manner that compression girder bodies with reinforcing ironsconstructed in the manner described are employed only for each secondrow. The compression girder bodies which are not provided withprojecting reinforcing irons can then be mounted on the pression girderbodies on reinforcing irons of the adjacent row of girder bodies, eachsecond row of such bodies may be provided with reinforcing irons whichonly project or which are bent over the ribs, and which may subsequentlybe bent upwardly about the compression girder bodies. 7

Finally, it is to be pointed out that the method according to theinvention can also be employed and a pair of floor panel bodiespositioned on opposed sides of the girder, the facing surfaces of thegirders and bodies being spaced apart at their upper ends and convergenttoward their lower ends to provide wedge-shaped spaces, rods embedded insaid bodies, said rods of the respective bodies having exposed portionprojecting oppositely across andiresting'on thetop of the girder tosupport the bodies thereon; and fillings filling the spaces between thegirders and bodies and embedding said exposed portions of the rods,

said opposite projecting rod portions having downwardly projectingportions arranged to enease the opp ite Sides of the girder, and extenincombination with known constructions. --Thu s,

more particularly for such roof parts where, in consequence of thegirders being difierently spaced, the existing pre-cast compressiongirder bodies cannot be used, or for fillingthe spacesbetween thecompression birder bodies and the wall, there .can be, -ernployed theknown construction with shuttering in which the whol compression girderpart is cast in concrete.

What I claim is: 1. In a floor construction, the combination ofrib-shaped girders, pre-formed arch-shaped bodies arranged between thegirders in the compression girder zone, means for suspending said bodiesfrom the tops ofsaid girders during the construction of the floon'saidmeans consisting essentially of rods embedded in said bodies and havingexposed portions bearing directly on the tops of saidgirdersthe'proximatesurfaces of the girders and bodies being spaced attheir upper parts and convergent toward their lower parts to providewedge-shaped spaces,-and a filling mass filling the space betweensaid'girders and bodies, said exposed portions being atleast partiallyembedded in said filling mass, at least one end of each of the said rodsbeing provided with a downwardly bent portion engaging over andaround-the upper end of the juxtaposed-girders and terminating in ahook-shaped portion on -w-hich the adjacent arch-shaped body is mounted.

2. In a floor construction comprising a girder sions on the saiddownwardly projecting portions on each of said bodies for supporting thebody on the opposite side of the girder.

3. In a floor construction, the combination of a girder and preformedbodies arranged on opposite sides of the girder, the sides of saidbodies and the facing sides of the girder being substantially plane andconverging downwardly one toward the other to provide downwardlytapering spaces therebetWeem-ai; least one reinforcing rod on eachpreformed body having one end embedded. in said body and another endprojecting beyond the said side thereof and supportably resting upon thetop ofthe girder, and fillings occupying said tapering spaces andembedding at least a portion of said projecting end of the reinforcingrods, said projecting end of some of the re-enforoing rods of each bodyhaving at least one part reaching to and depending: along the far sideof the girder and having a lateral projection supportably engaging underthe lower edge of the other preformed body.

. 4 In a floor-constructioncomprising a girder, apa-irof floorpaneibodies positioned on opposite sides'of the girder, rods embedded insaid bodies, said rods of the respective bodies having portionsprojecting oppositely across and resting on the; top of the girder tosupport the adjacent ends of the bodies thereon, said oppositelyprojecting rod portions extending downwardly on opposite sides of thegirder, and lateral projections on the downwardly extending portions ofat least one of said bodies for supporting the body on the opposite sideof the girder.
